Authenticated User 'Read' Permission

I have one of my AD users that keep getting 'Read Only' every time they try and open a file on a network drive. I discovered that in this users security in AD under 'Authenticated Users' the 'Read' box is checked. I am not seeing any other users with this box checked, so I tried unchecking this 'Read' setting and had the user try again. Boom, everything worked great after that. One problem though, the 'Read' check keeps coming back after a short time. I cannot get rid of it.

Any ideas?

I would suggest running a Group Policy Results report against your domain controllers, to see if a group policy is being applied that overrides your manual setting.

Thank you for the suggestion, asavener. However, there is only one GP in this OU that 200 others also share and they do not have the issue. For some reason, only this one individual.
You could always try creating a new account for the user.  (Just change the usernames on the original account.)

So far, I haven't had much luck resolving this issue. Can someone tell me this - where does the "Authenticated Users" group get its permissions from? The reason I ask, any changes I make to replicate another users "Authenticated Users" permissions within the same OU, always set themselves back to what they were before the change was made.

Where am I seeing this?
AD --> OU --> User --> Properties --> Security Tab
The access permissions on the user object are going to have nothing to do with the access the user has on a file-level object.  Check the permissions on the file or folder, and see what permissions the user has.  Make sure the user account is a member of the appropriate security groups.

This issue will be closed. The resolution was the result of having the 'Preview Pane' option turned on in file explorer in office. When the user opened the documents, the preview locked the file. By turning the preview pane off, the issue was fully resolved. Additionally, research proved that this is a bug in Office 2010.
